In addition, this version now runs in either Python 2.7 or Python 3.6. Previous users can remain with their current installations. New users are encourage to install the latest Anaconda version using Python 3.6

For Mac users, some users have had problems running TG successfully. This version has been tested with the latest OSX (High Sierra) and latest Anaconda releases of both Python 2.7 and 3.6. It runs with one quirk easy to circumvent. On a Mac, don't maximize any of the windows. And, when a user stretches a window, strange artifacts appear in the window. Selecting any of the action boxes on the window clears the problem.

I just downloaded Anaconda 3.6 and TG6.4 and followed the instruction posted on AAVSO. When I try to open the TG6.4.pyw file, nothing happens. Has anyone else experienced this? I have tried uninstall and re-install a few times. I have also tried Python 2.7 to no avail. Any tips?
